Dark Matter And Dark Energy by Brian Clegg

The Hidden 95% of the Universe

An accessible tour of the cosmic mysteries that dominate the universe, explaining how unseen matter and a repulsive energy rose to prominence in modern cosmology. It traces the evidence from galaxy rotation curves, gravitational lensing, the cosmic microwave background, and supernova surveys; surveys competing theories, experiments, and simulations; and assesses what is established, what remains speculative, and how upcoming observations might clarify the universe’s composition, fate, and the limits of human understanding.
